iThis is a great help for outdoor measuring. The integrated pointfinder (viewscreen) shows the target on the display. The device measures in the middle of the cross hair, even if the laser dot is not visible. Parallax errors occur when the pointfinder camera is used on close targets, with the effect that the laser appears dis-placed in the crosshair. In this case rely on the real laser dot.
